DUMP-CAR.

SPECIFICATION forming' part of Letters Patent N0. 719,794, datedFebruary 3, 1903.

Application led September Z0, 1901. Serial No. 75,932. (No model.)

To @ZZ whom it may concern.-

Be it known that I, HARRY STILLsoN HART, a citizen of the United States,residing at Chicago, in the county of Cookand State of Illinois, haveinvented certain new and useful Improvementsin Dump-Cars, of which thefollowing is a specification.

This invention relates to that class of cars known as dump-cars, andparticularly to 1o the construction thereof by which adumpcar of largecarrying capacity is obtained, al1 of which will be more fullyhereinafter set forth.

The principal object of this invention is to provide a dump-car with alongitudinal A- shaped hopper portion, swinging side hopper-boards, andvertical side boards arranged considerably above the hopper to obtain anautomatic dumping-car of larger carrying zo capacity.

Further objects of the invention will appear from an examination of thedraw-ings and the following description and claims.

The invention consists principally in a dump-car in which there iscombined a-sup porting-frame portion, side boards therefor, and anA-shaped portion arranged longitudinally of the car, with its apexsubstantially at the longitudinal center thereof and at the 3o ordinaryfloor-level, the leg portions of which extend downwardly and outwardlyto a point substantially outside the supporting carwheels. y

The invention consists, further, in the combination of asupporting-frame portion provided with the usual car-wheels, verticalside boards, an A-shaped hopper portion arranged longitudinally of thecar, with its apex substantially at thelongitudinal center there- 4o ofand at the ordinary floorlevel, the leg portions of which extenddownwardly and outwardly to a point substantially outside thecar-wheels, and swinging hopper-boards depending downwardly and inwardlyto meet the leg portions, complete a pair of (or twin) hoppers, and formdischarging-doors therefor.

The invention consists, further and finally, in the features,combinations, and details of construction hereinafter described and 5oclaimed. l

In the accompanying drawings, Figure lis aside elevation ofva portion ofa car constructed in accordance Withthese improvements; Fig. 2, a planview of the same looking at it from above and showing the parts arrangedto form a twin-hopper dump-car; Fig. 3, a longitudinal sectionalelevation taken on line 3 of Fig. 2 lookingin the direction of thearrow; Fig. a, a cross-sectional 6o elevation taken on line of Fig. 3,showing the parts arranged to form' a twin-hopper dumping-car of maximumcarrying capacity; Fig. 5, a cross-sectional elevation taken on line 5of Fig. 3, showing the parts arranged 65 to form a flat-bottomed gondolacar; and Fig. 6, a cross-sectional elevation showing a part of themechanism taken on line 6 of Fig. 3 looking in the direction of thearrow and with the inclined end board laid in a flat plane.

In illustrating and describing these improvements I have onlyillustrated and described that which I consider to be new, taken inconnection with so much as is old as will properly disclose theinvention to others and enable those skilled in the art to practice thesame.

In constructing a dump-car in accordance with these improvements I makea supporting-frame portion, which is preferably com- 8o posed of a pairof side sills a, center si-lls b, end sill c, cross-beam d, andintermediate sills e, all arranged to receive the shocks incident to theuse of and distribute the same throughout the proper elements of thecar. To provide for the carrying of the load, a pair of vertical sideboards f is secured to the supporting-frame or underpinning andpreferably connected together for purposes of stiffening at their endportions by a pair of ver- 9o tical end boards g, which, as shown inFig. 3, is secured to and rests upon the end sills.

To provide for the automatic dumping of the load and at the same time toform a largecapacity car, an A-shaped-hopper portion is provided andarranged longitudinally of the car, with its apex h substantially at thelongitudinal center thereof. It will also be noticed from au inspectionof Fig. 8 that the apex is arranged substantially at the ordinaryfloor-level and not only provides a car of large carrying capacity, butone in which the entire load will discharge itself, and thus dispensewith all of the manual labor of shoveling. The legs t' andyl of thisA-shaped portion, as shown in Fig. 4, extend downwardly and outwardly toa point substantially outside of the supporting car-wheels-that is, allof the load discharging over 4such legs will pass to a point outside ofsuch wheels, thus providing for a car that may carry any material thatit is desired to discharge outside of the trucks and prevent thederailing of the car. To complete the hopper portion-that is, to form apair of (or twin) hoppers-a pair of swinging hopperboards 7c isprovided, hinged, preferably, to the under side of the side sills anddepending downwardly and inwardly to meet the leg portions abovedescribed. only complete the twin hoppers, but they also form thedischarging-doors therefor. A pair of shafts Z Z is provided andconnected to the swinging hopper-boards by means of the chains m m,which act to lock such boards in position or permit them to be opened.These shafts should be provided with ratchet-andpawl mechanism (notshown) to prevent their being operated only at desired times, all ofwhich is understood in the art. An inspection of Fig. 3 will show thatthe supporting carwheelslimit the length of the twin hoppers and thattherefore some means must be provided for carrying the load above thewheels and permitting it to be automatically discharged when desired. Toaccomplish this result, a pair of inclined end boards In n is providedand inclined substantially from the apex of the A-shaped portionupwardly and over the car-wheels to a point adjacent to the stationaryvertical end boards. This arrangement, it will be seen, eifectuallydispenses with all manual shoveling. To still further increase thecarrying capacity of the car whenever it may be desirable or necessary,a foldable extension p is provided for each side board, which in oneposition is folded upwardly (see Fig. 4) to rest on the upper edge ofthe side boards and provide for the carrying of the maximum load, whilein a second position (see Fig. 5) they may be dropped downwardly andsubstantially out of the way.

At times it is quite desirable, and indeed necessary, to provide for theconversion of this type of car into a gondola car. To provide thenecessary elements for this conversion, a pair of supplementary sideboards qq are made and arranged to be raised in a vertical plane andform, as it were, supplementary side boards for the twin hopperin oneposition (see Fig. 4) orlaidina {iatplane and form a portion of thebottom of a gondola carin a second position. (See Fig'. 5.) Thesesupplementary side boards may be provided with These swinginghopper-boards nothooks (not shown) to more effectually hold them intheir vertical position. The inclined end boards (see Fig. 3) are alsoheld foldably in position by means of the struts r, which may be removedby withdrawing the connecting-pins s, and thus permit such end boards tobe laid in a dat plane and complete the bottom of a gondola car.

I claiml.
